x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32
|
|
|
|
Starting from binutils commit bd7ab16b4537788ad53521c45469a1bdae84ad4a:
|
|
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=bd7ab16b4537788ad53521c45469a1bdae84ad4a
|
|
x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
|
|
32-bit PC-relative branches. Grub2 should treat R_X86_64_PLT32 as
|
|
R_X86_64_PC32.
